Bootstrap 現行（v3.3.5）と新版（v4-alpha）で使われているclass一覧を見てみよう

比較してみたかった。微妙に数が合わない気もするので間違ってたら教えてください…:frowning:
**なお、どちらも`bootstrap.css`内にあるclassのみ一覧にしてあります。**

脱Bootstrapするときに「これってBootstrapのclassだっけ？自分で当てたclassだっけ？」と困ったらどうぞ。

# 感想
modalのshadowがなくなったり、btnにoutlineのclassが追加されたりと、フラットになっています。navbarも現行のと比べると、listの幅が狭くなってかなりシンプルです。
一番嬉しいのは、IE8を切ったことですね。これによって`em` `rem`が使えるようになりました。やったぜ。
一番悲しいのは、弊社のサービスではBootstrapを使いつつIE8対応しないといけないことですね。
